ART OF FORMING CHEEK-PIECES FOR BRlDLE-BITS SPECIFICATION forming partof Iietters Patent No. 258,166, dated May 16, 1 882."

Application filed December 10, 1851. (No model.)

To all whom it may concern:

Be it known that we, THOMAS E. VAN N ESS and DANIEL MALONEY, of Newark,in the county of Essex and State of New Jersey, have invented certainnew and useful Improvements in the Method of Forming Cheek-Pieces forBridle-Bits and we do hereby declare that the following is a full,clear, and exact description thereof, reference being bad to theaccompanying drawings, making a part of this specification, in which-Figure l is a perspective view of two blank cheek-pieces as they leavethe forming-dies. Fig. 2 is a like view of one of the same after the finor surplus metal has been trimmed away. Fig. 3 is a perspective view ofI said cheek-piece after having passed through the finishing-die. Fig. 4is alike view of the dies used for forming said blanks. Fig. 5 is aperspective view of a blank cheek-piece, in which the parts are arrangeddifferently from that before named. Figs. 6 and 7 show respectively saidblank after trimming and the completed article, and Fig. Sis aperspective view of the dies employed for producing said lastnamedblank.

Letters of like name and kind refer to like parts in each of thefigures.

Heretoforeit has been customary to formthe cheek-piece of a bridle-bitfrom a bar of iron having one of its ends bent around in the form of acircle, which blank was then heated to a welding temperature andsubjected to the action of dies within a drop; but such method hasproved objectionable from the fact that it has been practicallyimpossible to make a perfectly-welded joint atthepoint where the coiledend of the baroverlapped thebody of the cheekpiece.

To remedy this difficulty and to render easy the production of a perfectsolid article is the design of our invention.

It consists principally, as an improvement in the art of makingcheekpieces for bridlebits, in raising said cheek-pieces in relief onopposite surfaces of a plate or bar by dies that, while producingsubstantially the proper form and dimensions in cross-section, shall, byan irregular or distorted line of the raised por tion thereof, give tothe ring or bow in one direction a reduced sectional area to bring thearticle in the ensemble within greatlyweduced limits, (whereby a savingin stock and in the cost of dies and in the power to operate the same iseffeotech) then trimming 0d thefins and intermediate plate of metal, andfinally opening out said ring or bow to its proper form and dimensions,substantially as hereinafter specified.

It consists, further,in the dies, substantially as and for the purposehereinafter shown.

In the use of our method we take square bariron having the relativeproportion of measurement in cross-section of thrce-eighths byfiveeighths of an inch, and after heating the same place it between twodies, A and B, and sub ject said heated bar to several blows of theupper die, A. Each of the dies Aaud B is provided within its face with ahalf-round recess, a or b, which corresponds in outline to the form of acheek-piece, O, with its ring part c and tail-piece 0 closed inward, soas to occupy'but little space laterally, which dies, operating upon theheated bar, as before described, produce the blank C shown in Fig. 1,the surplus metal being forced horizontally outward in each direction inthe form of a tin, 0 The blank 0 passes from the forging-dies totrimming-dies, which remove the tin c and leave it in the form shown inFig. 2, al'ter which the ring part c is spread and given the form of acircle by dies, or by any other desired means,

such operation completing the forgingof the cheek-piece and producingthe article shown in Fig. 3. r l

There are various other forms in Which'the ring part and tailpiece maybearranged in order to cause them to occupy little lateral space and toenable them to be forged from a narrow bar of iron, and it willsutticiently illustrate the principle to describe one of such forms.

In Figs. 5, 6, and 7 are shown respectively a blank chcekpiece beforetrimming, the same after trimming, and the completed cheek-piece, and inFig.8 the (lies used'for forming said blank, the latter being amodification of the blank before described, and having its tailpiecebent around beside and parallel with the ring part, instead of beingextended lon gitudinally beyond the same. This form ofblank is not,however, deemed as advantageous as that shown in Fig. 1, as wider ironis required for its production and there is more waste from trimming.

The form-of blank shown in Fig. 1 permits the production at the sametime of two within one pair of (lies, as seen in Fig. 4, withconsiderable economy as regards waste of material. Two of the blanksshown in Fig. 5 may 31S0 'l)6.])l0(lll0(d at one time by one pair ofdies; but less economy results in the latter than in the former case.

Having thus fully set forth the nature and merits of ourinvention, whatwe claim as new lS 1. As animproveinent in-the art; of makingcheek-pieces for bridle-bits, raising said checkpieces in relief onopposite surfaces of a plate or bar by dies that, while producingsubstantially the proper form and dimensions in crossseetion, shall, byan irregular or distorted line of the raised portion thereof, give thering or bowin one direction a reduced sectional area to bring thearticle in the ensemble within 20 greatly-reduced limits, (whereby asaving in stock and in the cost of dies and in the power to operate thesame is effected.) then trimming ofl' the fins and intermediate plate ofmetal, and finally opening out said ring or how to its proper form anddimensions, substantially as specified.

2. The dies, as described, and shown in Fig. 4, substantially as and forthe purpose shown. In testimony that we claim the foregoing we havehereunto set our hands this 1st day of December, 1881.
